• Query about AD8497 Output

    Hi, there

    I have a question about AD8497. I used AD8497 for Type K thermocouple. I put thermocouple into the mixture of ice and water, which should be 0°C. However, the output of AD8497 shows it is 5°C. I tried with many temperature points. It shows…

  • RE: AD8497 with mux

    Hi garryp4,

    Thank you for your interest in AD8497. AD8497 should be able to accept inputs from multiplexed thermocouples. For more information on multiplexed thermocouples, please see page 7 of AN-369 or page 10 of AN-274. These application notes use…
